A device (10) is provided for the processing of collected saliva for direct use in an immunoassay. The device (10) suitably comprises a receptacle (11) with flexible walls for receiving an amount of saliva. The receptacle (11) is inter-engageable with a filtration device (13) which has an integral dropper mechanism (14). The filtration device (13) has a number of layers of a filter material having a gradation of pore sizes which permit passage of immunoglobulins while retaining mucous, tissue and food debris contained in saliva. An absorbent pad (17) mounted on a handle (18) can be used to collect saliva and transfer it to the receptacle (11), whereupon handle (18) is snapped off at a weakened line (19). Squeezing of the receptacle (11) facilitates release of immunoglobulins into a buffer whereupon the device (10) is inverted so as to allow filtration of the saliva to take place. |
